14 Claims.

My invention concerns sashes and window frames. One object of my invention is to provide .sashes which may be readily removed from a window frame for purposes of replacement, cleaning or repairing. My invention is therefore particularly useful in connection with sashes for screen and storm windows which are seasonally replaced.

A further object of my invention is to provide means on a sliding sash which retain said sash in the allocated position while it is slid up and down in the frame, but which still allows the removal of the sash fromthe window without l6 diflicult mechanical operation.

Another object of my invention is to provide sliding window sashes which may be slid up and down in a suitable window frame to substantially the full extent thereof, while in use; which however, can readily be removed from the frame.

It is also an object of my invention to provide, in combination-with light window sashes which can readily be removed from a window frame, means which securely retain said sashes at any level of their sliding range without necessitating the use of counterweights.

A further object of my invention is to provide a rugged, strong and simple structure for attaining the objects of this invention. I also 80 provide a window frame for replaceable sashes which may be superimposed upon a window, in

the casing thereof. c

Other objects will be revealed in and become moreclear from the following description and 85 from the accompanying drawings, in which Fig. 1 shows the perspective front view in ele- 45 Fig. 4 shows a sectional, horiaontal section.

taken on the line 4-4 of Fig. 2; the sashes being removed from the frame.

' Fig.5 shows, in a view similar to that of Fig. 3,

a modified form of my invention.

Fig. 6 shows from the inside an elevation of a modification of the novel :frame and sashes of my invention. A section of the top rail of the frame-and the..right sides of the.sashes. ,a're

broken away. I 5| Fig. 7, and Figs. 8 and 9 show corresponding side views of the top sash and of the bottom sash and frame, respectively, the two latter being cross-sectioned, the frame of Fig. 9 being positioned in a window'casing and the sashes of Figs.

7 and 8 beingtransversely exploded from said 5' frame.

Similar numerals refer to similar throughout the various views.

The window frame shown in Fig. 1 is to be mounted in a window casing, e. g. superimposed from the outside upon the ordinary window in parts said casing. The sides 6 and I, the top ,8 and the base 9 of said frame are rectangularly assembled behind the outer lining ll) of the frame, said lining being for instance flashed onto the outer face of said casing (not shown). In its side view (Fig. 2) said frame faces outward to the left, inward to the right.

A tongue'll. extends around the inside 'of the lower part of the frame and is mounted upon-20- the inside of the sides Band I and of the base 9 of said frame. A tongue ll fits into a groove l2 which extends around the lower sash I3 in the stiles I4 and I5, and in the lower rail l6 of said sash. A tongue l1 extends from the inside ofthe upper part of the frame in a manner equivalent to that in which the tongue II is arranged in the lower part of the frame, but it is outwardly offset in respect to the tongue -ll, so that the upper sash l8, which engages upon said tongue by means of a groove l9 extending around the stiles 20 and the upper rail 2| of said sash operates in the outward half of the frame substantially parallel to the lower sash l3, which operates substantially in the inward half of the frame.

The tongues II and I! are provided with I flanges 22 which rectangularly extend from said tongues and by means of which said tongues are fastened upon the inner walls of the frame. The parts of the flanges 22, which are mounted upon thesides 6 and 'I of the frame, are providedwith' regularly spaced clearances, through which protrude the center parts of the flat springs 23 into frictional engagement upon the stiles of the sashes I3 and ill, the free ends of said flat springs being siidably retained below said flanges 22 in suitable grooves in the sides 6 and I of the frame. In'the sashes l3 and H! are mounted window panes 24 or screens 25, and upon the .rails of the sashes are mounted handles or lifts 26 which facilitate the operation; of the sashes.

-Upon the-'upDenrails 21,.and 2| of the two sashes l3 and I8, are mounted, horizontal rods 28 which extend from both sides of said sashes into suitable grooves or runways 28 and 38 in the frame, respectively. The free ends of the rods may either fit these grooves, as indicated in Fig. 5, or they may carry 'rollers 3| of such diameter that they fit the width of said grooves, as indicated in Figs. 1 and 3. The runways 28 and 38 are connected at their lower ends, at the center of the frame, by a transverse groove 32,

inside face thereof.

From a slit in the top 8 of the frame hingedly depends a latch 33 which servesas a stop for the inner, lower sash l3, when said sash is slid in the frame. When that latch is swung around its fulcrum into a horizontal position, it clears the inside of the frame, so that the lower sash may be fully slid up in said frame. When the lower sash is thus slid allthe way up in the frame, the grooves l2 in the stiles l4 and I5 of said sash are disengaged from the tongue whereas said grooves are still engaged on said tongue, when the upper rail 21 of the lower sash |3 strikes the lower end of the latch 33' in its depending,. vertical position. When the latch 33 is in a horizontal position, and the lower sash I3 is slid all the way up in the frame,as described before, so that said sash is not engaged upon the tongue ii any more, the lower end of the lower sash may be pulled inwardly out of the frame, the upper end of the sash being still engaged upon the frame because the free ends of the rods 28, or the rollers 3|, which are journalled uponsaid free ends, are still engaged in the runways 29. When the lower end of the lower sash is thus withdrawn from the frame, the sash swings around the rods 28 and. may be swung around these fulcrums into a substantially horizontal position. If the lower sash is then lowered, while extendedin a horizontal position, the free ends of the rods 28 or the rollers 3| slide or roll down in the runways 29 into the groove 32. When the free ends of the rods, or the rollers are in the groove 32, the sash may be withdrawn from the window frame, since said groove 32 opens inwardly from the frame. It is thus seen that the free ends of the rods 28 or the rollers 3| guide the upper end of the lower sash along the vertical track of the runways 29 as long as the lower sash is in the window, and these free ends of the rods or rollers aid the tongue ||,which, as

such, guides the sash only in the lower part of the frame,in securely slidably retaining the lower sash along its whole range of movement in the frame. The lower sash is therefore guided in the frame along its whole length atall times, except when it is raised to its very highest position.

To the extent to which the upper rail 2'! of the lower sash l3 and the lower rail 38 of the upper sash l8 vertically overlap each other, they are provided with horizontally overlapping strips 35, (the strip on the rail 34 does not show in the drawings) which serve to close the space between said sashes, when said sashes are in the fully closed position of Fig. 1. Such strips are of course not necessary when the sashes themselves are in sliding abutment upon each other in the frame. But the friction of the sashes upon each other, while sliding up and down in the frame, is reduced, if the only places of abutment are the strips 35.

The upper sash I8 is slidabie upon the tongue l1, when it is in the upper part of the frame,

whereas said sash is vertically guided, when it is in the lower part of the frame, outwardly by the outer lining lot the frame, and inwardly by the lower sash l3.

After the lower sash |3 has been removed from the frame, the upper sash may be removed from the frame in the following manner:-

It is slid into its lowest position, the rod 28 or the roller 3| of said rod travelling along the runway 38, until it drops into the groove 32, when which opens at the front of the frame from the said sash has reached its lowest position. Since the lower sash has provisionally been removed from the frame, the upper sash can now be moved along the groove 32 into the runway 29.

The upper sash is nowlifted up to its highest position, the rod 28 on the upper end thereof, or the rollers 3| on said rods, travelling along the runway 28. When the rod 28 or the roller 3| is at the upper end of the runway 29, the lower end of the upper frame l8 may be swung inwardly above the tongue into a vertical position, the rod 28 serving as a fulcrum around which the sash is swung. The upper sash Hi can now'be removed from the frame in the same manner the lower sash has been removed before, i. e., the sash is lowered in a horizontal position, the rods 28 or the rollers 3| travelling along therunway 29, until they finally are withdrawn from the frame through the groove 32 v structed in a great number of modifications;

reversing the arrangement of tongues and grooves on the frame and on the sashes would be one such modification.

In the modification of Fig. 5 the insides of the frames are substantially completely covered with I sheet metal, the tongues II and I1 being produced by folds in said sheet metal. The sheet metal serves also as a lining in the runways for thefree end of the rod 28, or the roller 3|, thus providing a smooth surface, for the sliding or rolling action of those parts, and at the same time strengthening the surfaces which are subjected to wear and tear.

The modification of Figs. 6, 7, 8 and 9 shows my invention in a very simple form.

The frame 5| extends around only three sides of my replacement window, and consists there- I fore of the sides or stile runways 52 and 53 and the top piece or connecting member 54. This frame is inserted from the outside in a window casing and suitably fastened in position. The sill remains clear (Fig. 9). v y

In Fig, 9 I face thewindow casing 55 from between my replacement window and the win-' dow proper 56, may drain outwardly over the sill 51.

A rim or staifhead 58 extends around the inside on the three sides of the frame, in alignment with the outward face thereof. This rim 58 extends alongside of the upper sash 59 (a screen in this case) and retains it in its fully lowered position in the frame in one outward direction;

but a groove 6| extends around three sides of said sash, andslidably fits over the tongue 62,

which extends aroundthe upper sides 52 and 53 and the top piece 54, upon the inside of the frame.

In a corresponding manner, grooves (not shown) extend in two opposite sides of the lower sash 60, and they are guided by the tongues 63, which are arranged upon the inside of the sides 52 and 53, at and near the lower end thereof.

In the manner described hereinbefore in respect to the other modifications, the guides 62 and 63 are transversely offset in relation to each other, the guide tongues 62 being arranged outwardly, and the guide tongues 63 being arranged inwardly, said tongues being relatively offset substantially to the extent of the thickness ofthe sashes.

Therefore the sashes 59 and 60, as shown in a dot-dash line in Fig. 9 in .a closed position, overlap in abutment upon each other. In its top position sash 59 is guided by tongue 52; in its bottom position between' rim 58 and sash 50.

If the lower sash Bills to be removed from the window, it is simply raised and taken out in an inward direction. In order to avoid that sash 60 drops out inwardly when raised, I prevent the said sash from being lifted to the highest position at which it is slid from tongues 53, again providing a latch 33, in analogy to the arrangement shown in Fig. 1 etc.

The upper sash 59 cannot be removed when the lower sash 60 is in the window. After the lower sash 30 has been removed from the window, I may remove the upper sash 59 by pulling it way down, until it has disengaged from the tongue 62 and then it may be removed, by being lifted out at an angle through the space or gap superimposed on the sides of the sashes, so to speak. In reality they are sunk into the grooves upon the sides of the upper and lower sashes, being flush with the bottoms of said grooves when depressed, their curved center parts bulging normally up onto said grooves, thus frietionally engaging the tongues 52 and 53, respectively.

While I have shown and described my invention with some degree of particularity, it will be realized that other modifications and changes may be resorted to under special conditions. I therefore do not wish to be limited and restricted to the exact details shown and described, but reserve the right to make such changes and modifications as may fairly fall within the scope of the subject matter now being claimed.
